NHLKING- Specification of Letters Patent.

MACH-NE.

Patented Dec. 1 1, 1906.

Application filed July 31,1906. b'ermi No. 328,546.,

Be it known that I, Looms BlJiiRi-1LL, a citizen of the United States, residing at Little Falls, in the county of ilerkimer and State of -New York, have invented a new and useful Improvement in Milkingliachines, of which the following is a specification.

This invention relates to that class of milk jug-machines in which the milk pail or re ceiver is connected with milking contrivances for milking two cows simultaneously. Ileretoforc the milk so drawn from two cows was counningled in the pail or receiver; but it is often desirable to keep the milk from each cow separate in order that the yield of each individual 'cow can be asccrtaincd and recorded hoth as to weight and quality.

The object of my invention is to provide simple and convenient means for cil'cctii'ig this result.

in the accompanying drawings, consisting oi' two sheets, Figure 1 is a sectional elevation oi a iniikmg-nnu-hine provided with my imrovemcnt. Fig. 2 is a horizontal section in line 2 2, Fig. 1. Fig. 3 is a vertical section at right angles to Fig. l in line 3 3 in that iigure. l 'ig. i is a horizontal section through the puisator in line 4 4, Fig. i, on an enlarged scale. Fig. is a vertical section through the pulsa tor in line 5, Fig. 4.

Like letters of rcl'cronce refer to like parts in the several iigurrs.

The milking-nnichine to which my improvement. is applied. as represented in the drawings, is of the general type which is shown and disclosed in my Letters Patent No. 784,750, March 14, W05. which type is selected for convenience in illustrating, the invention; but the invention in its hroad aspect is also applicable to other styles of milking-machincs.

It represents the milk pail or rcceivcr upon. which the milking couirivanccs, suitable for milkin two cows simuliancousiy, are mountcd. any suiiabie consirm-iion and comprise,

bricily stated, and so i'aras shown in ihe drawings. a lop plate 11, which covers the pail and i ightly but rcmovaiviy sccurcil thereto:

an upright uiisatair-cylinder i), mounted centrally on said top plate and having two oppiisiiclvwxtcndiug nipples-l1 \\'ili1 which the two milk-pipes connect which lead in the teat-cups t, and which are prclcrably each These milking contrivam'cs may he of composed of a glass tube c, a rubber hose 0, and a cock 0; a puisator-piston or valve 1), which is moved up and down in the cylinder and which is connected by a rod (1 with a liexihlc diaphragm c in a casing E above the cylinder; andv a suction-pipe f, which connects the pail or receiver with the exhaust or vacuum mechanism.

The pulsator piston or valve D is provided with .two separate ports or channels 9, Figs. 3, i, and 5, which in the upper position of the piston (shown in Figs. i and 5) coincide with the nipples b and the milk-pipes and open downwardly into the pail or receiver A, so i that the suction applied to the milk-pail operates through the ports or channels 9 and the miikpipes upon the two sets of teat-cups, while the milk from each cow passes separately through each pipe and the corrcsponding port or channel 5/ to the pail.

\Vhen the piston or valve D is in its lower position, (represented in Fig. 3,) the ports or channels 9 are out of line with the nipples, and the communication between the exhausted milk-pail and the milk-pipes and teat-cups is cut oil', thereby cutting oil the suction from the teatcups.

The pail or receiver is provided with a partition H, which divides the pail into two compartments, side by side, and which extends as nearly to the top of the pail as practicable, the partition having preferably a central. notch or depression h in its upper edge to clez the pulsai1or-pision in the lower position of the latter. The two milk ports or channels g of the pulsator piston or valve are arranged on opposite sides of this partition, so that ti o milk is discharged from each port into the corresponding compartment of the pail, thus keeping the milk from each cow separstc.

For discharging ihe milk i rom each c0mpertinent oi the pail separately and convenientiy the pail is provided near its top with i two dischargc-spouis ii, which are prel'erablv provided with removahiicaps or stoppers Z. These spouts are arrulig'iii side by side on the some side of the pail and on opposite sides of the partition, but tni-ar i,l1ii:iti1,:1ll(l preferaliy div'crgc outwardly. The milk contained in the pail is readily poured out separately from each compartment through these spouts into two ordinary pails or vessels placed side by side, .yherehy the milk trom end it pulsator-vslve arranged above said ess The plsil A is provided Wi til the usual bail M and audio N for manipulating it, end the plate 6 of the pulsstor is provided wits the usuel'beil O.

I claim as my invention- 1. In a inilkin -mschine, the combination of e receiving-pail having milkeompsrtments arranged side by side and a milking mechanism mounted on said pail and provided with means for milking two cows simultaneously, said milking mechanism having two separate milk-passages, each opening into one of said compartments, substentislly as set forth,

2. In a milking-machine, the 'oonibinetion of e receiving osil havingmillocompertments arranged side by side and e milking mechanism mounted on said peil and provided with means for milking two cows simultaneously, ssid milking mechanism comprising a pulsetor-velve having two. separate milk-passages, each opening into one of said compartments, substantially as set forth.

In a mi1king-n1eel1i11e, tl1e combination of a receiving-pail having an upright pertition dividing the psil into twocompertments,

partition and provided with separate mill;- pesssgesopening into the pail on opposite sides of said partition, substantially as set i'ortl1.

In it milking-machine, the combination of e receiving-pai having an upright partition dividing thepail; into twocompertments, an upright pulsstor-cylinder arranged above said i ertition, and a verticel l-y-lnovsble pulsetor-piston arranged in said cylinder and provided itn seperste milk-ports on opposite sides of said partition, substantially as set forth.

in s milkingmiool'une, the combination r oeiving-psii having milloccmpsrtments ranged side by side and clisrge-spout for each compartment, and a willing mechanism mounted on said pail and ,iovided with means for milking two cows simultaneously end with separate millopassages, one for each compartment, ubstsrr tie-11y as set forth.-

T ngleeline, the combination g-ps l. having an upright psrtition dividingthe pejl' into two compartments and having dischergespouts on opposite sides of said partition, and a pulsstor mechanism mounted onssid psil, and nevi g sepsrete Inilk-pssssges opening into said pail on opposite sides or said partition, substsntielly as set forth.

7. In a milking-machine, the combination of e reoei ing peii having an upright pertition dividing t'nepeil into @WQCOBZEHL-Iflii13&llt$ and having discliergespouts arranged. side by side on the some side. of the psil near ti top thereof and on. opposite of said partition, and mean for delivering the milk from two cows separately into thopail on opposite sides of said partition, substantially as set form Witness my hand tlii 27th day of July, 1906.
